title: [Study of serological and biological markers in viral hepatitis. 157 hemophiliacs].
abstract: We observed for a two years period 157 hemophiliacs (138 with hemophilia A whose 13 were severe and 19 with hemophilia B whose 13 were severe) and we studied the incidence of liver dysfunction and the role played by HB and non-A, non-B, viruses. Whereas 32 patients not related had no evidence of serological HB virus markers (by radioimmunoassay), 88 (70,4 %) among the 135 hemophiliacs with large or small exposure to blood products were "HB positive". 90,9 % were positive for anti-HBs and anti-HBc antibodies and only two patients had persistent antigenemia. These results appeared independent of the kind of treatment (factor VIII or factor IX concentrates). Six among 17 children born since 1974, when the antigen was detected by RIA, had the serological HB virus markers, showing that this method is not sufficient to completely eliminate the HB virus. However the amount of viruses injected is too small to induce an acute hepatitis and rather produces specific antibodies which protect hemophiliacs against reinfection. An elevated level of serum transaminases (SGPT) was observed in 9,4 % of non treated hemophiliacs, 15,1 % of treated hemophiliacs with no serological markers of HB virus and 27,7 % of treated hemophiliacs "HB positive". This shows that the use of concentrates and the occurring of HB virus in the patients are not the only factors producing liver dysfunction. The role of non-A, non-B viruses has been recognized in 7 patients out of 9 with transient elevation of serum transaminase levels, by Trepo with an immunodiffusion technique.
